Install Ubuntu One

[Option 1] Install Ubuntu One from the command line:

Enter your password at the password prompt if requested. It should look like this:

[sudo] password for user: where user is your login name. It does not show any echo characters when you type your password.

It may prompt you with a question like this: Do you want to continue [Y/n]? The capitalized option in brackets is the default choice, so you can just hit enter, type y and enter, or n if you changed your mind.

[Option 2] Install Ubuntu one using Muon Software Center

Open Muon Software Center from your application launcher.

Type ubuntuone-control-panel-qt in the search box in the upper right corner.

Click on Ubuntu One. Two buttons should appear; click on the one that says Install.

Make Ubuntu One start when KDE starts

Open your KDE autostart folder in Dolphin. It should be ~/.kde/Autostart (which is short for /home/user/.kde/Autostart) unless you moved it.

Runningubuntuone-control-panel-qt --with-iconwill start the Ubuntu One in the system tray, but it will also open a window. Instead, runubuntuone-control-panel-qt --minimized at KDE start to start the system tray.*

Click File > Save as... and browse to your autostart folder. In the Name: box enter ubuntuone.desktop. See more about Desktop File Specification and the file name

The file name should end with.desktopand should not have spaces.

Go to Dolphin that you opened earlier and right-click on the file you just created and select Properties.

Under "Properties for ubuntuone.desktop — Dolphin" click on the Permissions tab.

Under "Access Permissions" look for "Is executable" and click on the check box if it is empty and click Okay.
